Clay barring is an important step in the detailing process. It removes contaminants from the surface of the paint that cannot be removed by washing alone. These contaminants can include brake dust, tree sap, and road tar. A clay bar is a pliable, non-abrasive material that is used to gently remove these contaminants.
To use a clay bar, first, wash the car thoroughly to remove any loose dirt or debris. Then, wet the clay bar and the surface of the paint. Next, gently rub the clay bar back and forth over the surface of the paint, using light pressure. The clay bar will pick up the contaminants and leave the surface of the paint feeling smooth.
